If the cutter is not moving when the cutter motor runs, there is probably a gear loose in the cutter mechanism. Take the machine to the dealer that you purchased it from, or the nearest authorized dealer. http://webservices.us.vsmgroup.com/DealerLocator.aspx?Brand=Viking
Make sure that you have your warranty card and purchase receipt. If a gear has broken, the mechanism is warrantied to the original owner for 20 years.
If you are the second owner, or the machine was purchased online instead of through an authorized dealer, an authorized dealer will give you an estimate for parts and labor and repair the problem for you.

Make sure that when your machine stops and cuts that your needle is in the upper most position. Other than that you may need an adjustment from a pro repairman.

Adjusting the timing of the thread trimmer cam
How to adjust the timing
The timing of the thread trimmer cam for cot ton and synt hetic threads can be obulned simply by aligning the marker dot on the machine ann and the marker dot on the handwheel.
Till the machine head. manually tum the handwheel un til the thread take-up lever almost reaches its highest
position . and press th read take-up picket to the right by finger. This causes the earn toller 10 fit
in the groove of the thread trimmer cam. With this condition maintained, tum the handwheel in the direction
opposite to the nonnal rot ational direction . and you will find a position in which the handwheel no longer
turns. Then, adjust the cam timing so that marker dot on the machine ann is aligned with
marker do t on handwheel This provides the proper cam liming for ca tion
and synthetic threads.
